Towards Healthy and Sustainable Diets: Understanding Food Consumption Trends in the EU.

The assessment of food system sustainability requires a profound understanding of the evolution of food production and consumption. Monitoring the transition towards healthier and sustainable diets is crucial for supporting future interventions. This study explores market sales data as an input to investigate and compare current dietary trends in the European Union Member States over 14 years. By analysing consumption trends of major food product categories, including animal-based and plant-based foods, we identified two distinct clusters of countries with opposite dietary patterns. Our analysis explored not only major food product categories essential for healthy living but also superfluous foods (i.e., discretionary) to provide a broader understanding of dietary habits. In particular, our results show that countries reducing consumption of animal-based foods also exhibit a reduction in consumption of discretionary products, such as alcoholic beverages and soft drinks, highlighting opportunities for synergies between environmental and health policies. This research provides valuable insights for policymakers and stakeholders aiming to promote the uptake of healthy and sustainable diets and supports the development of targeted strategies to support the transition towards more environmentally friendly and healthy food systems.
